Microbial communities play important roles in soil health, contributing to processes such as
the turnover of organic matter and nutrient cycling. As soil edaphic properties such as …

Soil organic matter (SOM) anchors global terrestrial productivity and food and fiber supply.
SOM retains water and soil nutrients and stores more global carbon than do plants and the …

Soil organic matter (SOM) is correlated with reactive iron (Fe) in humid soils, but Fe also
promotes SOM decomposition when oxygen (O2) becomes limited. Here we quantify Fe …

Reduction–oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like
most soil properties and processes, redox is spatiotemporally heterogeneous. However …

Electron transfer (redox) reactions, mediated by soil microbiota, modulate elemental cycling
and, in part, establish the redox poise of soil systems. Understanding soil redox processes …

Iron oxides are important structural and biogeochemical components of soils that can be
strongly altered by redox-driven processes. This study examined the influence of temporal …

While most bacterial and archaeal taxa living in surface soils remain undescribed, this
problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in …

Ferrous iron (FeII) oxidation is an important pathway for generating reactive FeIII phases in
soils, which can affect organic carbon (OC) persistence/decomposition. We explored how …

The response of mineral-stabilized soil organic carbon (SOC) to environmental change is a
source of uncertainty in the understanding of SOC cycling. Fluctuating wet-dry cycles and …

Iron (Fe) minerals play an important role in carbon (C) and nutrient dynamics in redox
fluctuating soils. We explored how the frequency of redox oscillations influence Fe reduction …
